I think "Tchoing" insincerely, or anything done insincerely, unless rehearsed makes one feel like an idiot.
I recall a scene from the classic martial arts movie "Enter the Dragon". Bruce Lee's character is fighting Chuck Norris' character, and Bruce's character has a habit of bobbing and bouncing on his feet. As Chuck's character begins to lose, he, too, starts bobbing and bouncing on his feet, imitating Bruce's character, and that is when Bruce's character knows he has defeated him. To me choing is the same. If I change my behavior to that of my opponent, because it seems to work for them, they have won. I need to do what works for me.
You need to maintain a ruthless, deep focus. To enter the zone, which is a very narrow ‘tunnel’ of utmost concentration.
If you need to pep up yourself by acting out aggressively, then so be it. For me, and other players if I understand what I'm reading as well, it's an inner thing. My zone is grounded in inner tranquility, not inner turmoil. So I don't act out, and if somebody else's hollering and other attempts to disturb me, than that's a shortcoming in my own ability to stay balanced and concentrated.
The strategy of countering that behaviour by replicating it would only aggravate things. It doesn't make much sense to give up on balance and tranquility in an attempt to regain it. Power to the shouters, but my zen is my own.
can't believe someone actually compares fake movie craps to a real sport situation. whats more, its Bruce's!
in the case of tchoing, it's necessary. believe me, I was once lost against a lower ranked one because of I was annoyed of his tcho.
I was able to gety groove back when I start tchoing back.
